Stainless Steel 317 Grade Products

Stainless Steel 317 (UNS S31700) is a molybdenum-bearing austenitic stainless steel with greatly increased resistance to chemical attack as compared to the conventional chromium-nickel austenitic stainless steel pipe such as SS 304 and SS 316L. In addition. SS 317 offers higher creep, stress-to-rupture, and tensile strength at elevated temperatures than conventional stainless steel tubing. SS 317L is a low carbon version of SS 317 grade which provides resistance to sensitization during welding and other thermal processes.Stainless Steel 317L is non-magnetic in the annealed condition but may become slightly magnetic as a result of welding.

    Principal Design Features


    317L is a low carbon version of 317 stainless. It possesses the same high strength and corrosion resistance and will produce stronger welds due to its low carbon content. Many users are shifting over to this alloy in lieu of 304 and 316 as availability and cost improves.





    Chemical and petrochemical process equipment, pulp and paper manufacturing and condensers in fossil and nuclear fueled power generation stations.




    Low speeds and constant feeds will minimize this alloy's tendency to work harden. Tougher than 304 stainless with a long stringy chip, the use of chip breakers is recommended.



    All common fusion and resistance methods except oxyacetylene welding have proven successful. Use AWS E/ER 317L filler metal for best results.


    Hot Working

    All common hot working processes are possible with this alloy. Heat to 2100-2300 F (1149-1260 C). Avoid working this material below 1700 F (927 C). For optimum corrosion resistance, a post-work annealing is recommended.



    Cold Working

    Shearing, stamping, heading and drawing can be successfully performed . To remove internal stresses, a post-work annealing is recommended.





    1850-2050 F (1010-1121 C), followed by rapid cooling.





    This alloy does not respond to heat treatment. Cold work will cause an increase in both hardness and strength.
